Application filed August 25 1906. Serial No. 331,980.

The object of my invention is toprovide-a simple and effective apparatus for treating liquids with chemical rea ents and to provide means whereby a su cient amount of chemical reagent s all be supplied to the action-tank, and preferably'at the point where or before it enters the'apparatus, to prevent any injury to the apparatus by means of any acid or other substances conparticular features of m invention are pointed out in the appende claims.

The accompanying drawings illustratean apparatus for the purification of water ivictih not desire, however, to limit my invention to apparatus for the purification of water, as it is apparent that my invention may be used 'in connection with apparatus designed for other urposes. v

' In t e accompanying drawings, Figure 1 is an elevation,'part y in section, of m provedapparatus. Fig. 2 is a plan vlew of the auxiliary water tank. Fig. 3 is an elevation, partly in section, of a portion of the lime-water tank,

"5- is an overshot water-wheel of the ordinary construction; 6, the shaft upon which the wheel is mounted and'which rotates with the wheel. 7 and 8 are beveled gears mounted upon to be treated before it enters the re-.

tank and a portion of the lime-' which lime-water-is drawn from the lime-water tank. I .Fig. 54 is an elevation," in section, of,. the waterwheel, box,

the gates through which thefwater the ime which it 1s necessary to supply to the water in order to properly purify it were sup- .point "where the li the apparatus, 'wlnc 1s composed of metal,will

the respective ends of, the shaft 6. A predetermined portion of the water which flows into the wheel-box 4 is discharged into the chute 9 through the adjustable ate, 9 and flows into the funnel 10 and t rou h the openin 11 into the pipe 12 and is disc arged t roug the openings 13 into the bottom of the lime-tank 14. The balance of the water flowi into/the wheel-box 4 is discharged throu the adjustable gate 15 and pipe 15 into t e reaction-tank 16.

By the means shown the water to be treated is supplied to the wheel-box and as it flows from the wheel-box is divided into two streams," bearing a relative predetermined proportion each to the other. One of these streams is fed to the lime-water tank and the other to the reaction-tank. The lime-water tank 14 is provided with two overflow-outlets, one, 17, discharging into the reactiontank 16, by means of thechute l8, and the other, 19, discharging into the auxiliary tank 20, which is located at the side of the lime-water'tank. These two overflow-open mgs are provided with'gates 21, b the lateral adjustment of which the over ow can be regulated. The. tank 20 is provided with a float 22 and a valve 23,.communicating with I a pipe 24.. When the liquid in the tank 20 has risen to a predetermined height, the float 22 opens the valve 23, and theliquid contained in the tank, which is usuall limewater when the apparatus is inten ed for the purification of water, is drawn by the pump 2 through the pip? 24 into the intakepipe 1, as the water to e purified enters the ap aratus.

n many cases the water to be purified containsacid, and if this is not neutralized at the aid enters the apparatus be uickly corroded and destroyed. If all of lied at this point, t e impurities contained 1.11 the water would be de osited in the form of precipitate, "which won d clog and foul the apparatus and seriously interiere with and finally interrupt its operation. I therefore by the regulation of the gate 19 supply to the water through the pipe 24 a suliicient amount of lime water to neutralize the acid, but not a sufiicient amount to cause any deposit of precipitate, the additional lime water necessary 25 the apparatus.

to complete the purification being supplied through the overflow-openin 17 and the chute 18 to the reaction-taut While the pump 2 is in operatiomit is constantly draw- 5 111g a supply of lime water from the tank 20.

If 1t 1s working rapidly, a larger amount of water to be purified is being supplied to the wheel-box 4, and consequently an increased volume is being supplied to the tank 14,

which causes an increased overflow into the tank 20, therebyraising the float 22 and opening to a greater extent the valve 23 and permitting a larger amount of liquid to be drawn therefrom through the pipe 24 to the i 5 water whielris passingtln-oug i the apparatus. If a lesser amount is being pumped through the pipe 3 to the wheel-box/a lesser quantity of water is being supplied to the tank 14, and the overflow into the tank is 20 likewise proportionately reduced, and I am enabled by Me means described to feed to the pipe 1 a proportionate quantity of lime-water irrespective of the quantity of water which is being pumped through the pipe 3 to 25 is a beveled gear mounted 1 pon a shaft 26, upon which are mounted agitators 27 for the purpose of thoroughly mixing the water and chemical reagents contained in the reaction-tank 16. 28 is a bev- 3o eled gear mounted upon the hollow shaft 12.
